mod_perl install error (build perl with -Dusethreads)

Hi All,

I have Apache/2.2.22 and Perl/v5.18.0 and setting up mod_perl/2.0.7.

While installing mod_perl I am getting the following error:


Ø  file /install/perl/v5.18/perl
gives
/install/perl/v5.18/perl: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped

Ø  Command to build mod_perl:
/install/perl/v5.18/perl Makefile.PL MP_APXS=/export/apache/bin/apxs

Ø  Result:
Reading Makefile.PL args from @ARGV
   MP_APXS = /export/apache/bin/apxs
no conflicting prior mod_perl version found - good.
Configuring Apache/2.2.22 mod_perl/2.0.7 Perl/v5.18.0
[  error] Using Perl 5.018000 w/o ithreads and 'worker' mpm httpd.
[  error] Failed requirements:
[  error]   - Perl built with ithreads (build perl with -Dusethreads)

As recommended in the last line - "build perl with -Dusethreads" I tried that while setting up perl but the same error.

Please share your inputs to resolve this.

Thanks,
Rommel.
